Patent CA-2308000-A1 (CA)
Inventor: KIENZLE MICHAEL
IPC: H04B10/40
Filed: 2000-05-10
Abstract: This invention relates to optoelectronic transceivers used in optical communication systems, and in specific to an optical transceiver configured for transmission and reception of optical signals or rays within an asymmetrically shaped optical profile. The invention provides a transceiver for communicating optical rays through relatively-positioned, shaped lenses while preventing the saturation of a photodetector by an adjacent LED, thereby avoiding any idling of the communication system, minimizing the transceiver's size, and isolating the optical profiles for optimum transmission and reception of optical rays. The transceiver may operate in a half duplex mode, while being capable of operating without additional modifications in a full duplex mode.

IPC: G10L21/02
Filed: 2000-11-24
Abstract: An adaptive noise suppression system includes an input AID converter, an analyzer, a filter, and a output D/A converter. The analyzer includes both feed-forward and feedback signal paths that allow it to compute a filtering coefficient, which is input to the filter. In these paths, feed-forward signal are processed by a signal to noise ratio estimator, a normalized coherence estimator, and a coherence mask. Also, feedback signals are processed by a auditory mask estimator. These two signal paths are coupled together via a noise suppression filter estimator. A method according to the present invention includes active signal processing to preserve speech-like signals and suppress incoherent noise signals. After a signal is processed in the feed-forward and feedback paths, the noise suppression filter estimator then outputs.a filtering coefficient signal to the filter for filtering the noise out of the speech and noise digital signal.

IPC: H04L12/24
Filed: 1998-12-15
Abstract: In a telecommunication controller (1), a messaging system allows real time communication between sub-systems such as a main controller (2) and line cards (3). Requesting applications (5) create a proxy (12) which controls the function call via a middleware engine (11) in each of the sub-systems (2, 3).  A resource middleware engine (11) calls a server (13) which in turn controls performance of the function on the resource (10). The proxies (12) are transient. The servers (13) are static but may be easily added or deleted according to resource changes. Applications (5) and resources (10) are decoupled from the messaging system.

Title: Intelligent-networked telecommunication system which strategically creates and employs service-dependent pseudo calling line identities to eliminate redundant billing errors
Inventor: CAI YIGANG
IPC: H04M15/06
Filed: 2001-02-12
Abstract: An intelligent-networked telecommunication system avoids redundant billing for telephone transactions in which there is a billing conflict between the Intelligent Network (IN) and another component of the system by its Service Control Point (SCP) creating a service-dependent pseudo Calling Line Identifier (CLI). When a Pseudo CLI look-up table stored in the SCP database indicates that a pseudo CLI is to be created (based upon the Desti-nation Number, DN, or the Service Key, SK), the SCP combines a prefix listed in the table with the Calling Party Number (CgPN) to form a pseudo CLI or create a totally new CLI number string. When the call is connected to the DN, the created pseudo CLI, rather than the original CLI, is trans-ferred to the DN. A pseudo CLI is indicated where the IN is programmed to handle the billing of a particular transaction, and where the instrumentality of the DN (e.g., toll switch or special service platform) is also set up to han-dle billing. When the toll switch, special service platform, etc., attempts to bill for the transaction (already being billed by the IN) the pseudo CLI pre-vents it from billing an actual customer since no actual customer will have any of the pseudo CLIs. The service-dependent CLI also indicates to the toll switch, or special service platform, etc., that the current IN service call has already been billed through the IN.

Filed: 1999-10-26
Abstract: A method of determining the propagation delay over a packet switched network  intented to provide a segment of a telephone circuit. In response to a reque st for a telephone circuit between two subscribers, a packet containing an echo  request message is transmitted over the packet switched network from a first  network node to a second network node. The second network node reacts to receipt of the echo request message by transmitting a packet containing an echo reply message to the first network node. The first network node then determines the round trip propagation delay for the packet switched network segment on the basis of the time which elapses between sending the echo request message from the first node and receiving the echo reply message als o at the first node.
